Description

[Detailed description of the invention] [Technical field] This invention relates to a heating type hair iron that forms curls and waves in the hair, and involves improvements in the material of the hair press plate attached to the back side of the hair curling rod. It is something that

[Background technology]

In this type of hair iron, if the hair curling rod with a built-in heater is connected and fixed to the grip case in an almost straight line, the whole iron becomes long and bulky, making it inconvenient to carry or store when traveling. It is.

Therefore, it has been proposed that the hair curling rod can be inserted into the grip case in a nested manner, and the overall length can be shortened when not in use (for example, Japanese Patent Publication No. 345 of 1983, Japanese Publication of Utility Model Publication No. 54 of 1983). Publication No. 8948). However, in this case, the grip case generally tends to be thicker than necessary, and depending on the size of the hair curling rod, the grip case tends to be too large for ease of use. In addition, the surface temperature of the hair curling rod reaches around 100 to 150 degrees Celsius immediately after use, so if you insert it into the grip case as it is, the grip case itself and the built-in parts will overheat and be adversely affected. be.

[Purpose of invention]

From this point of view, this invention has been developed in a hair iron so that even when the hair is curled immediately after use, there is no heat effect on the grip case and its built-in parts, and there is no need to make the grip case unnecessarily thick. The primary purpose is to fold it into a short size for convenient carrying and storage. In addition, even if the hair curling rod is hot immediately after use, it can be folded safely without the risk of burns, and it can be placed in a travel bag or special storage case without causing heat damage to other items. The second purpose is to

[Summary of the idea]

In order to achieve the above object, the present invention adopts a conventional form in which a hair curling rod 2 equipped with a hair presser plate 3 on the back (top) side can be stored in a nested manner within a grip case 1, as shown in the drawings. Instead, the hair wrapping rod 2 equipped with the hair presser plate 3 is in a posture extending in a substantially straight line in front of the grip case 1 when in use, and from this state, the hair wrapping rod 2 equipped with the hair presser plate 3 is in a position extending substantially in a straight line in front of the grip case 1. It shall be pivotably connected so that it can be folded approximately parallel to the . After that,
The entire hair press plate 3, or at least the outer surface side, is made of a thermally poor conductor. Examples of the poor thermal conductor include heat-resistant plastic, rubber, wood, and mat members containing glass fiber. In such a case, you can immediately fold the hair wrapping rod 2 into the grip case 1 by placing your hand on the hair press plate 3 without getting burned after use, and moreover, in the folded state, the grip case 1 and the hair press plate 3 can be folded together. Since the hair curling rod 2 is sandwiched between the two, it is possible to immediately put it into a travel bag or a special storage case without causing any trouble.

〔Example〕

The drawing illustrates a hair iron according to the present invention, which is comprised of a grip case 1, a hair curling rod 2 and a hair press plate 3, which hold the hair in place to form curls and waves on the hair.

The entire grip case 1 is formed into a longitudinally elongated cylindrical shape, and is preferably made of a heat-resistant plastic material with left and right divided cases 1a and 1b.
are overlapped and integrally connected with front and rear screws 4, 4. A lead wire 6 connected to a power cord 5 is inserted into the interior of the grip case 1, and a recess 7 is formed in the ventral (lower) side of the case 1 in the longitudinal direction.

The hair curling rod 2 is made of a metal pipe and has a built-in heater (not shown) connected to the lead wire 6.
A rod base 8 made of a heat-resistant material is integrally connected to the proximal end of the rod 2. The rod base 8 is fitted into the front end of the grip case 1 and is rotatably connected around a shaft 9 surrounding the screw 4. It is rotatable around the axis 9 between the usage position shown in FIG. 1 and the position shown in FIG.

The hair press plate 3 has an arcuate cross section, is attached to the back (upper surface) side of the hair winding rod 2 in a state that closely covers it along the longitudinal direction thereof, and rotates together with the hair winding rod 2.

What should be noted here is the material of the hair presser plate 3.
As shown in FIGS. 4 and 5, the illustrated example has a cross-sectional structure in which a thermally defective conductor 3b is integrally laminated on the outer surface side of a metal substrate 3a. come into contact with. The thermally defective conductor 3b is made of a heat-resistant plastic material such as phenolic resin, and is formed into a sheet and pasted or coated and integrated. Of course, other materials with excellent heat insulation and heat resistance, such as rubber, wood, and glass fiber-filled mat members, can also be considered, and a multilayer structure of two or more layers can be implemented as necessary. Incidentally, when the substrate 3a is made of a metal plate with good thermal conductivity as in the illustrated example,
Although it is advantageous for heating and curling hair by sandwiching the hair between the substrate 3a and the hair curling rod 2, in the present invention, the hair presser plate 3 is entirely composed of a heat-resistant conductor. It also includes the form.

This hair holding plate 3 has an operating plate 1 having a groove-shaped cross section at the base end.
The operating plate 10 is pivotally connected to the rod base 8 with left and right shafts 11, 11 so as to face a spring receiving box 14 integrally formed on the rod base 8. A return spring 12 is interposed between the operation plate 10 and the spring receiving box 14, and the elastic force of the return spring 12 presses the hair press plate 3 so that it always comes into close contact with the back surface of the hair wrapping rod 2. Forced. When the operation plate 10 is pushed down against the force of the return spring 12, the hair press plate 3 rotates around the shaft 11, and its tip side floats upward and away from the hair wrapping rod 2. In addition,
The spring receiving box 14 enters into a recess 13 formed at the rear upper part of the shaft 9 at the front end of the grip case 1 when the hair curling rod 2 is in a substantially straight position as shown in FIG. .

In FIG. 3, a locking means is provided between the grip case 1 and the hair wrapping rod 2 to hold the rod 2 in a substantially straight position in use. The illustrated lock means includes a lock receiving piece 15 projecting rearward from the rear end of the spring receiving box 14 of the rod base 8, and a lock pawl 16 sliding in the front and back direction behind the recess 13 of the grip case 1. The lock pawl 16 is moved forward and urged by the spring 17, and the tapered tip 16a of the lock pawl 16 is inserted into the recess 1.
This protrudes into the lock receiving piece 15 and engages with the upper surface of the lock receiving piece 15, thereby holding the hair wrapping rod 2 in a substantially straight position in front of the grip case 1. In the figure, reference numeral 18 is an operation knob integrated with the lock pawl 16, which faces the top surface of the grip case 1.

When the lock pawl 16 is slid backwards with the knob 18 in hand and the tapered tip 16a is disengaged from the lock receiving piece 15, the hair wrapping rod 2 moves around the shaft 9 together with the rod base 8 and the hair press plate 3. Then, it is rotated approximately 180 degrees in the direction A in the figure, and a folded state is obtained in which a part of the circumference of the hair wrapping rod 2 is inserted into the recess 7 on the ventral side of the grip case 1 as shown in FIG. The hair rod 2 is held in a folded state. As the holding means, for example, a form can be considered in which the tip of the hair wrapping rod 2 is fixed to the grip case 1 using a stopper 19 such as a ring or a band formed integrally with the arm 5a of the power cord 5. Of course, this type of stopper 19 may be integrally formed with the grip case 1, and the holding means is not particularly limited.

When the hair wrapping rod 2 is rotated approximately 180 degrees in the opposite upward direction from the folded state, the rod base 8
The spring receiving box 14 fits into the recess 13 on the grip case 1. At this time, the spring receiver box 14
The lock receiving piece 15 at the rear end presses into contact with the tapered surface of the tapered tip 16a of the lock pawl 16, and the lock pawl 16 is temporarily retreated against the force of the spring 17, so that the lock pawl 16 moves into the recess. At the same time, the lock pawl 16 slides forward by the force of the spring 17 and engages with the lock receiving piece 15, so that the hair curling rod 2 is held in its original substantially straight position in use. .

In addition, in the folded state of the hair wrapping rod 2 as shown in FIG. 5, the lateral side portion on the circumferential surface of the hair wrapping rod 2 is the lower end portion 1c of the grip part case 1 that covers the upper circumferential surface of the hair wrapping rod 2; It is desirable that it be located inside the line L that connects the end 3b of the hair press plate 3 that covers the lower circumference of the hair curling rod 2. In this case, it is possible to effectively prevent hands or other objects from touching the hair wrapping rod 2 from the sides in the folded state.

Further, since the recess 7 is effective for folding the hair rod 2 without adding bulk, it is possible to extend a heat insulating material on the outer surface of the inner bottom of the recess 7 as necessary. .

[Effect of idea]

As explained above, according to the hair iron of this invention, the hair curling rod 2 is rotatably and pivotally connected to the grip case 1 so that the hair curling rod 2 can be folded toward the ventral side of the grip case 1. At the same time, a hair press plate 3 mounted on the back side of the hair wrapping rod 2 in a manner covering it rotates together with the hair wrapping rod 2. Therefore, it can be folded into a compact state when not in use, making it convenient to carry and store.

Furthermore, the grip case 1 does not need to be made thicker than necessary, so it is easy to use. Since the hair wrapping rod 2 exists outside the grip case 1 in the folded state, the grip case 1 and its built-in parts can be well protected from heat immediately after the hair wrapping rod 2 is used.

In addition, since at least the outer surface of the hair presser plate 3 is made of a thermally poor conductor, even when the hair curling rod 2 is hot immediately after use, you can place your hand on the hair presser plate 3 and hold the hair curler rod 2 on the hair presser plate. 3, and even if the hair iron is placed in a travel bag, storage case, etc. immediately after the folded state, the hair curling rod 2 under heating can be folded between the grip case 1 and the hair presser plate 3. Since it is sandwiched in between and not exposed to the outside, it will not cause heat damage to other objects.
